Teacher's Guide For: Water Temperature and Salinity Experiment
Students experiment with water density, temperature and salinity. For this water lesson, students observe how the coldest water sinks to the bottom of a test tube, and how saltwater sinks in comparison to freshwater.
Curated OER
Water World Story
Fourth graders write a story about how a drop of water may have traveled to school. They design a presentation on the water cycle.
Curated OER
The Weight of Water
Students participate in an experiment about the weight of water. They work together to discover that seawater is more dense than fresh water. They also determine which objects float and sink.
